Bottom Round Roast (Lean Budget Slow-Roast)
By Steve Mitchell · Carnivore Enthusiast + Podcaster · Updated 2026-05-09
Bottom round is a 3-4 lb lean roast at $5-7/lb. Slow-roast at 200°F for 90 minutes to 130°F internal, then sear. 28g protein, 5g fat per 100g cooked.
Bottom round roast is a 3 to 4 pound lean cut from the rear of the cow at $5 to $7 per pound — among the cheapest beef roasts available. The cut is too lean for high-heat fast cooking; it dries out fast above medium-rare. The right technique is slow-roasting: 200°F oven for 90 to 120 minutes to 130°F internal, then a 90-second sear in a smoking hot cast iron. A 4-ounce cooked slice delivers 32g protein, 5g fat, and 190 calories — the highest protein-per-calorie ratio of any beef roast. A 3-lb bottom round feeds 6 to 8 adults at $18 to $25 total. Because the cut is lean, finishing each slice with a generous pat of butter is essential. Leftover slices make the best beef sandwiches (when not on carnivore) or salad-bowl meat — the slow roast preserves moisture better than oven-baked roast beef ever does.

Instructions
- 1
Salt the entire roast generously (about 2 tbsp for a 3-4 lb roast). Refrigerate uncovered on a wire rack for 12-24 hours to dry-brine.
- 2
Take the roast out 1 hour before cooking. Pat surface dry with paper towels.
- 3
Preheat oven to 200°F. Insert a probe thermometer into the thickest part of the roast.
- 4
Roast at 200°F until internal temperature reaches 125°F. For a 3 lb roast this takes 90 to 105 minutes; 4 lb takes 110 to 130.
- 5
Pull from the oven. Crank a cast iron skillet over high heat until smoking.
- 6
Sear all sides of the roast for 60 to 90 seconds per side. The crust should be deep brown.
- 7
Rest 10 minutes. Slice as thinly as possible (⅛-inch) across the grain.
- 8
Top each portion with a pat of butter while the meat is still warm.

Frequently Asked Questions
Can I cook bottom round at higher heat to save time?
Not without losing the texture. Above 250°F oven, lean cuts like bottom round contract their muscle fibers fast and squeeze out moisture. The 200°F slow phase is what keeps the cut tender — there's no shortcut for this specific muscle. If you need to speed up, a sous vide bath at 131°F for 3 hours produces similar results in a less hands-on way.
Bottom round vs eye of round vs top round — which is best?
All three are lean rear-quarter roasts at similar prices. Eye of round (29g protein, 5g fat per 100g cooked) is leanest and most uniform. Bottom round (28g, 5g) has slightly more flavor due to a heavier muscle workload. Top round (28g, 6g) is between the two. For slow-roasted carnivore eating, bottom round wins on flavor; eye of round wins on uniform slicing.
Can I use a slow cooker?
Possible but the texture is different. Slow cooker bottom round at low setting for 6 to 8 hours produces a soft, shreddable texture more like pot roast than sliceable roast beef. For the recipe above (sliceable medium-rare), oven-roast at 200°F is the right method. Save the slow cooker for chuck roasts that have enough fat to stay moist over long wet cooking.
